Radiation is frequency dependent

(A video is being downloaded in case you're wondering why there is no picture.)

Below also shows cone break-up shape at different frequency in 3D form.

Due to cone break-up, where by the break-up is dependent on frequency over dimension, weight and shape, therefore the sound output radiation is un-predictable and random. This makes the speakers completely non user-friendly (engineer friendly) as we do not know where it shoots more sound (louder) and unknown what kind of sound (frequency) ???.

All speakers behaves like this :(


  1. Loudspeaker

  2. Signal Path

  3. Anatomy

  4. Voice Coil

  5. Sound Representation on Scientific Terms

  6. 3D movement of 13.8Hz

  7. 2D movement 13.7Hz

  8. But no speaker is perfect

  9. Because of Cone Break-up

  10. Radiation is frequency dependent

  11. Radiation Field

  12. Therefore no speaker has flat frequency response

  13. Why do we need flat frequency response?
